1. A delivery system for implantation of a self-expanding stent within a body lumen, comprising:

  • a delivery assembly includingan elongated catheter having proximal and distal ends, the distal end configured to receive on an exterior thereof the self-expanding stent;

    an elongated sheath having proximal and distal ends and formed with a lumen to slidably receive the catheter, and having an open-ended receptacle at the distal end for receiving the self-expanding stent;

    a manipulator having a stem axially movable relative to the manipulator, the stem connected to the proximal end of the sheath to adjust an axial position of the sheath relative to the catheter, and wherein the proximal end of the catheter is selectively positioned to engage the manipulator, wherein the manipulator further includes a handle having a hollow tube receiving the proximal end of the sheath, the handle having an elongated slot through which the stem extends, and the handle having a distal end adjustable connected to the proximal end of the sheath; and

    a stop disposed on an exterior of the catheter proximal to the self-expanding stent to prevent the stent from moving proximally during relative movement between the sheath and the catheter; and

    a guide catheter having a proximal end, and formed with a lumen for receiving the delivery assembly therein, and wherein the proximal end is connected to the manipulator.
